HNF150 SPRING 2014 Learning Objectives Week 12 1 According to Michael Pollan why is there an quotillusion of food diversityquot in American supermarkets According to Michael Pollan people go into super markets or restaurants and look at the abundance of different foods to choose from However he says that if you look at the ingredients list you will see corn soy and their derivatives are in most of the products on the market It can be hard to nd a food product that does not contain a product of corn Also only a few companies own most of the brands that we see in the supermarket 2 How can bacteria become transmitted from the environment found in CAFOs into the food we eat When cows are fed corn instead of grass they are more susceptible to getting sick and can become infected with Ecoli Bacteria can be transmitted from cow to cow and from their feces to the meat The manure contaminates many things like the cow39s skin as well as the feed that the cows consume This can be a major problem because it can cause Ecoli in meat products which is a highly virulent bacteria Ecoli has been found in apple juice spinach meat or many other products It can contaminate the applesspinach or other plants through the runoff of manure contaminating water sources and the soils where plants are grown 3 How have labor practices in the meat packing industry evolvedchanged since Upton Sinclair s quotThe Junglequot was published in the early 19005 After quotThe junglequot was published labor practices for meat packers improved such that it was one of the most protected and highest paid jobs in the US Today however legal protections for workers in the meat packing industry have declined Many companies hire illegal workers from Mexico An example was given from a company in North Carolina Oftentimes when raids are done the companies are not nes but instead the illegal workers at the companies are put in jail and sent back to Mexico The company just nds more illegal workers to take their place 4 Identify some of the hidden costs of a factory farming system How do these costs compare to those of a large scale organic farming system Laboreconomic animal welfare and environmental costs are some of the hidden costs of a factory farming system One poultry house can have between 280000 and 300000 henschickens This means that sanitation and welfare could be large issues with so many animals in such a small place HNF150 SPRING 2014 Learning Objectives Week 12 Oftentimes workers are treated the same way with no regard to their safety from dealing with carcasses that may be diseased The companies that own the poultry houses or are in contract with them force them to upgrade their equipment even if in order for the farmers to keep their contract The farmers know that they cannot compete with the company if it terminates their contract Also there is a lot of use of pesticides that may contaminate food sources In some organic farming systems animals are free roaming and grazing which leads to natural fertilization of the elds and the animals are eating in a way that supports their health Pesticides are not used and organic farmers support the organic matter of the soil which reduces soil erosion and conserves water 5 Describe the hidden costs to cheap food both environmental and health costs One hidden cost is to peoples39 health The cheap food uses cheap ingredients like high fructose corn syrup and lots of sugar which are unhealthy to consume in large quantities People who eat this kind of food regularly are at a greater risk of hypertension or diabetes which increases medical costs from doctor visits and medications This is a leading cause of obesity in America The environment is another cost due to soil erosion and contamination of other plants or areas Mass production of corn and other food needs large equipment that emit green house gases and other pollutants that further cause damage to the air and environment 6 Discuss the bene ts of grazing versus grainfed animal production for human and animal health Animals that are grazed on grass are healthier get sick less often and require fewer antibiotics Having the animals defecate on the grazing lands acts as a natural fertilizer eliminates the need for manure swamps and prevents manure from contaminating water sources and other elds 7 List the reasons why farmers and ranchers use antibiotics with livestock and the potential harms for human health Antibiotics are used to prevent animals from getting sick to treat animals that are sick and also are used a growth enhancers animals grow faster and bigger when antibiotics are added to their feed Recent research suggests that humans may also grow faster and bigger with antibiotic use Such widespread use of antibiotics can cause the generation of antibiotic resistant bacteria that can infect people the HNF150 SPRING 2014 Learning Objectives Week 12 antibiotics that people are given from their doctors may not work against them
